Abstract

PURPOSE:To obtain bound spun yarns, by feeding fibers prepared by opening a sliver to a rotor, and twisting the resultant fibrous bundle by a turning air current. CONSTITUTION:A sliver 100 fed to a feeding roller 13 is opened by a combing cylinder 12, and the resultant opened fibers are led to and deposited on a deposition surface 7 on the inside of a drum rotor 3 rotating at a high speed on an air current in a passage 10. The successively depositing fibrous layers are drawn out one after another into a fibrous bundle 103 by drawing the fibrous bundle 103 connecting to the fibrous layers. The resultant fibrous bundle 103 is then brought into contact with a circular arc surface 41 of a deflector 40 provided just after the depositing surface 7 and false twisted and bound. The resultant fibrous bundle 103 is then guided to a constricted passage 31 of a twisting nozzle member 29 and twisted by an air current jetted from a nozzle 28 of the passage 31 to give the aimed yarn 104.

Description

DETAILED DESCRIPTION OF THE INVENTION According to the present invention, the core of the yarn is a parallel and discontinuous fiber bundle,
The binding thread that has been bundled with other fibers twisted on its surface is further added with a binding thread that twists the entire system in the direction in which the fibers on the surface are twisted. This involves a binding spinning method and apparatus for obtaining bundled yarns made by combining yarns.0 The binding spinning method involves passing a divided fiber bundle called a fleece through a heating device, and passing it through a heating device on the upstream and downstream sides of the heating device. By heating the fiber bundle between the gripping points provided by the action of the swirling air flow formed in the heating device, the fiber bundles are twisted in opposite directions upstream and downstream of the heating application point by the swirling air flow. In this method, the fiber group located at the edge of the fleece, which is a discontinuous body of fibers, receives the heating effect later than the fiber group located at the core when receiving the heating effect of the swirling air flow. When the fiber bundle is sent from the upstream side to the downstream side of the heating point and subjected to the untwisting action, the fibers in the core part of the fiber bundle are untwisted to form a part with little or no twist, while the fibers located in the edge part The fiber group, which was heated less than the core, is given a main twist in the opposite direction to the twist given upstream of the heating point, and is wrapped around the fiber group in the core. This type of binding spinning method does not allow the Isosaki that gives the twist to be lightweight and can be heated and spun at high speeds, but conventional roller draft In this method, the splitting speed of the draft part that forms the fleece does not correspond to the heating speed for forming the binding yarn, and it is difficult to obtain a draft with a magnification that is equivalent to the heating rate for forming the binding yarn. Draft verts that use a draft bar have durability problems and cannot withstand continuous operation for long periods of time, requiring constant attention to maintenance and maintenance of the equipment.

On the other hand, in the open-end spinning method, the sliver is opened into individual fibers, and the opened fibers are fed together with an air stream to a drum rotor having a deposition surface, and the fibers are deposited on the deposition surface by the action of centrifugal force. The fiber bundle is deposited in layers, peeled and drawn out as a continuous fiber bundle, and twisted by the rotation of a drum rotor, so it has the feature of being able to be heated and spun at high speed. Therefore, when spinning thin filaments at high speeds, the centrifugal force becomes excessive and the fiber bundles tend to break, so it is said that spinning a large count is economically advantageous.

An object of the present invention is to provide a binding spinning method and apparatus that can perform hot spinning at high speed by speeding up the formation of the fleece.

Further, in the present invention, in order to form the fleece, a flow of individual fibers obtained by opening the sliver is supplied to a drum rotor and converged, and a heating effect is applied to the converged fiber bundle by a swirling air flow to form a binding yarn. It is an object of the present invention to provide a method and apparatus for spinning knots.

Another object of the present invention is to provide a binding spinning method and apparatus that further twists the binding yarn formed by the heating effect of the swirling air flow in its entire length direction.

A further object of the present invention is to provide a binding and spinning method and apparatus for adding heat to the binding yarn formed by the heating effect of the swirling air flow and for doubling the binding yarn into two yarns.

According to the present invention, individual fibers obtained by opening a sliver are deposited in a layer on the bale surface formed on the inner surface of a drum rotor that rotates with the airflow, by the action of centrifugal force. The fiber bundle is further stripped to form a continuous fiber bundle, which is deflected in an arc by contacting an arcuate surface of a deflector to flatten the fiber bundle, and then passed through a cylindrical channel of a guide part of a guide device; The twist formed between the deflector and the take-up roller is heated by the swirling airflow formed in the cylindrical passage, and the twist applied between the contact point with the deflector and the heating application point of the swirling airflow is the heating application point. The yarn is untwisted between the roller and the pick-up roller to form a binding yarn, and is twisted by 10 as the drum rotor rotates.

8. Cheese 59 is provided according to conventional methods.

The knot spinning method of the present invention will be explained using the embodiments of the present invention described above.

A sliver 100 is placed between the supply roller 15 and the planosaur 15.
When the sliver 100 is supplied, the sliver 100 is supplied to the surface of the combing cylinder 12 by the rotation of the supply roller 16 in the direction of the arrow, and by the rotation of the cylinder 12 in the direction of the arrow, the sliver 100 is opened into individual fibers 101 by the combing cylinder 16, and air is The air flow supplied to the passageway 10 carries it in a stream towards the deposition surface 7 formed on the inner surface of the drum rotor 3 which is being driven in rotation.

Since the deposition surface 7 is recessed with an arcuate cross-section, the air flow is redirected over the deposition surface 7, so that the fibers 101 are deposited on the deposition surface 7 in a layered fiber layer 102.Drum rotor When the air on the surface of the deposition surface 7 is sucked through the suction hole 52 opened to the deposition surface 7 in the fiber 101 , the suction force of the suction air flow is
Reinforce the shiitake.

At the beginning of the spinning process, when the seed yarn is brought to the pile surface 7 of the drum rotor 5 through the cylindrical channel 27 of the guide section 25 of the guide device 19, the weft yarn ends are deposited on the pile surface 7 by the rotation of the drum rotor 3. The fiber layer 10 on the deposited surface 7 is bonded to the ribbon-shaped fiber layer 102 (see FIG. 2) and is
2 is peeled off and continuously pulled out as a fiber bundle 105. The fiber bundle 103 passes through the cylindrical passage 27 formed in the guide portion 25 of the guide member 19, is pulled up by the pick-up row 257, and is rolled up on the cheese 59, and as will be described later. Deflector 4 immediately after being peeled off from deposition surface 7
The guide member 19 (
b) Twisting is applied in proportion to the rolling speed.

Heating nozzle member 29 provided in the guide portion 25 of the guide member 19
The fiber bundle 105 guided through the conical opening 30 and the narrowed passage 31 is subjected to suction caused by a jet air flow ejected from the air chamber 26 of the guide section 25 from the injection nozzle 28 formed in the heating nozzle member 29. The air flow acts and provides a traction force T towards the cylindrical passage 27 of the heated nozzle member 29 .

Due to this traction force T, the fiber bundle 105 is pressed against the arcuate surface 41 of the deflector 40, and between the point where the fiber layer 102 is peeled off from the deposition surface 7 of the drum rotor 5 and the contact point B to the arcuate surface 41. Due to the existence of an angle α between the line M-B of
T-shape), the fiber bundle 103 is connected to the arcuate surface 4 of the deflector 40.
1, the fiber bundle 103 is flattened between the point M and the point Of leaving the arcuate surface 41 and widened by a maximum of +% w-+ at the point °C. In FIG. 4, the fibers 10 corresponding to the hexagonal fibers 7 and the deflector 40 between the fiber opening and the heating nozzle member 29 are shown.
1. It shows the shapes of the Bile a layer 102 and the Maki fiber 105.

The injection nozzle 2 is inserted into the cylindrical passage 27 in the heating nozzle member 29.
The jet stream emitted by 8 causes the fiber bundle between the drum rotor 5 and the nozzle 28 to be twisted in the same direction as the twist imparted to the iron tubule 103 by the rotation of the drum rotor 6. Circular air flow in the direction of adding shi to circle WJ?
It is preferable to form the passage 27. However, the rotation axis of the drum rotor.

Depending on conditions such as the ejection pressure and drawing speed of the jet air stream, a swirling air stream may be formed in a direction that imparts twist in the opposite direction to the twist imparted by the rotation of the drum rotor. .

The fiber bundle 105 which has been expanded and guided into the Japanese commercial passageway 27 by contact with the deflector 40 has a central portion of the fiber bundle 1060 in one direction on the upstream side of the heating fF point of the swirling beam airflow. A strong twist is applied to the fiber groups located at the edges of the fibers, and a weak twist is applied to the fiber groups located at the edges far from the center, and when this false twist is untwisted downstream of the heating point,
The heating in the center is almost completely removed, and the fibers located at the edges are twisted in the opposite direction to the heating direction, that is, twisted in the opposite direction to the twist given by the rotation of the drum rotor 5, and the core is The fibers are wrapped around each other to form a so-called binding thread.

Formation of such a binding yarn occurs between the portion where the fiber bundle 103 contacts the deflector 40 and the gripping point of the pick-up roller 57, and between the above, the entire length of the fiber bundle 106 is caused by the rotation of the drum rotor 3. The associated twist is applied over the entire length, resulting in heating nozzle member 29
The threads 104, which are twisted over the entire length of the threads bound together by the action of the swirling air flow inside, are shaped into a shape and wound onto the cheese 59.

Considering the relationship between the rotational speed N of the drum rotor 5 and the rotational speed Nun of the guide member in the above spinning method, the rotational speed N of the drum rotor 6 is such that the individual fibers 101 that have been opened are piled up on the drum rotor 5 due to centrifugal force. The yarn 1 is sufficiently uniform to be deposited on the surface 7 and peeled off as a fiber bundle 105.
This is the rotational speed that forms the fiber layer 102 with the doubling required to form 04. To give an example of one continuous rotation condition, in consideration of providing sufficient doubling to spin a uniform yarn, when using a drum rotor 3 with an inner diameter of 100 degrees on the deposition surface 7, The minimum rotational speed is about 1000 r, p, m. In this case, the difference n between the rotational speed N of the drum rotor 3 and the rotational speed 1+n of the guide member 19 corresponds to the drawing speed of the thread 104, and if the drawing speed is set to 200 m/min, n is approximately 635 r, p. , rn. Therefore, if the rotational speed of the drum rotor 3 is N=1000 r, p, m, the rotational speed of the guide member 19 is N + n = 1
655 r, p, tn.

In carrying out the method, when the rotation speed of the drum rotor is set to 5000 r, p, tn, the rotation speed of the guide member 19 is set to 600 or, p, m, and about 10
It is preferable to drive the guide member 19 to rotate at a high speed of Llu r, p, m in the same direction as the drum rotor 3.

Also, the distance li1 between the stripping point A of the fiber bundle 106 of the drum rotor 5 and the contact point B of the fiber bundle 103 of the deflector 7
．． Stable spinning can be achieved by setting l equal to Ml contained in the sliver 100 and the average fiber length of the fibers.

FIG. 5 shows a cross-sectional view of another embodiment of the invention.

In this embodiment, the same parts as in FIG. 1 are denoted by the same reference numerals, and the explanation thereof will be omitted.

In this embodiment, at the upper end of the base 20 of the guide member 19, another support pA 124 extends in the radial direction at a position 180 degrees apart from the support arm 24 shown in FIG. 1 with respect to the axis 0-0. A hollow cylindrical guide portion 125 is formed at the outer end of the support arm 124 in the radial direction.
A recess forming an air chamber 126 is carved in an annular shape on the inner periphery of the
In addition, a heating nozzle member 129 having a cylindrical passage 127 and an injection nozzle 128 formed therein is tightly fitted and fixed to the inner periphery of the guide portion 125, and a heating nozzle member 129 is formed between the recess and the outer periphery of the heating nozzle member 129. The air chamber 126 is connected to the injection nozzle 128, and the passage 149 formed in the support arm 124 is connected to the base 20'! It communicates with the passage 48 provided with 5P, and is designed to produce a jet air flow that generates a swirling air flow in the cylindrical passage 127 from the injection nozzle 128.The dimensions of each part of the heating nozzle member 129 and The central axis direction of the circular passageway 127 is all the same as that of the decorative nozzle member 29.

Further, in this embodiment, the recess 11 is provided in the nousing 1.
Another recess 111 is formed at a position 180 degrees apart with respect to the axis 0-0, and the combing roller 1 is inserted into the recess 111.
12. A supply roller 115 and 115 pressers are arranged to be pressed against the supply roller 115 by the elasticity of the spring 114.
411 formed on the circumferential surface of the combing roller 112
The fibers 101 opened by 6' or button cloth are arranged so that the air flow carries the fibers 101 from the air passage 110 to the deposition surface 7 of the drum rotor 5.

That is, in this embodiment, a flow of fibers 101 is supplied to the deposition surface 7 from two locations separated by 180 degrees with respect to the axis 0-0 for one drum rotor 6 which is made into a rotating part within the housing 1. The guide member 19 is provided with guide portions 2 having exactly the same structure on the top of the base 20 at positions separated by 180 degrees with respect to the rotation center axis of the base 20 via support arms 24 and 124, respectively.
The fiber bundles 1.03, 105 are peeled off and pulled out from the stacking surface 7 of the drum rotor 3 by heating nozzle members 29, 129 provided in each guide portion 25. Part 29゜129
At the same time, the whole length is twisted by the rotation of the side drum rotor 3.

Therefore, in this embodiment, the two yarns 104, 104, which have been bound together by the effect of the swirling airflow as described above and are twisted over their entire length, are passed through separate yarn guides and take-up rollers. When winding into separate cheeses, the production of binding threads can be doubled with one rotor compared to the embodiment shown in FIG. 104, 104 are merged into one yarn guide 156 as shown in FIG.
When the cheese 159 is picked up by the pick-up roller 18.7, the pick-up roller 157
The two yarns 104 and 104, which are bundled and twisted as they pass through, can be further combined to obtain a yarn 105.

As explained in detail above, the spinning method of the present invention includes a means for opening the supplied sliver into individual fibers, and a drum rotor for rotating the opened individual fibers around a central axis of rotation. means for supplying the fibers to the inner deposition surface of the drum rotor to deposit individual fibers in a layered manner on the deposition surface by centrifugal force; The deposited fiber layer is peeled from the end portion of the deposited surface by a guiding means that rotates in the direction of (b) to form a continuous round wire bundle, and the fiber bundle is pulled out and twisted in proportion to the rotation of the guiding means. between the deposition surface of the drum rotor and the guide means, the fiber bundle peeled off from the deposition surface and pulled out is caused to undergo at least one curved direction change to increase the width of the core-fine bundle; a means for spreading, and a fiber bundle pulled out by the guide means and expanded in width, partially imparting a turning motion to the circumference in the length direction to false-twist the fiber bundle, and when the false-twisting is untwisted; It consists of a heating means for forming a bundle of fibers, in which individual fibers that have been spread out are formed into a layer by centrifugal force on a deposited surface formed on the inner periphery of a rotating drum rotor to form a fiber bundle. Since this is done by depositing the yarn and peeling it off from the end, a doubling effect similar to that of a rotor-type open-end spinning machine can be expected, and it is possible to spin yarn with excellent uniformity and improve focusing. Since the spinning is performed by a drum rotor and the twisting is performed by a swirling air flow, high-speed spinning is possible. After separation, the continuous fiber bundle formed by being peeled off from the stacking surface of the drum rotor is removed by engaging a deflector in a direction substantially perpendicular to the length direction of the fiber bundle before the swirling air flow acts on the fiber bundle. By changing the direction in a curved manner at least once, the width of the fiber bundle is widened, and the fibers located at the edge of the fiber bundle are subjected to centrifugal force due to the direction change, causing one end of the ridge/fiber to be It generates so-called fibers that are freed from the constraints of the fiber bundle, so that during local heating by the swirling air stream, the fibers located at the edge of the fiber bundle have less mechanical strength than the mechanical fibers located in the core. After the false twist is untwisted, the fibers located at the edge, especially the exposed fibers, can be tightly wound around the birch fibers located at the core to create binding. In addition, since a twist proportional to the rotation of the guide means is added to the entire length of the bundled yarn generated by the heating of the swirling air flow, the bundled bundle has a very fine yarn quality. It is something that can be formed.

Furthermore, in the spinning method of the present invention, one
The deposited fiber layer is peeled off and two continuous fiber bundles are drawn out by two guide means spaced 80 degrees apart, and each of these fiber bundles is bound and guided by the swirling air flow. To Shun, who performed the twisting process proportional to the rotation a, said 2
When the fiber bundles of books are spliced together, it is possible to form yarns that are even stronger and have a unique texture.

In the above method, when the swirling airflow is ejected in the direction of pulling out the fiber bundle, the force that presses the fiber bundle against the deflector is reinforced, and the airflow is applied through the ventilation hole opened on the stacking surface of the drum rotor. By this, when the centrifugal force to deposit the fibers on the narrow deposition surface of the drum rotor is insufficient, the deposition due to the centrifugal force can be compensated for.

Furthermore, the spinning device of the present invention includes a housing, a fiber opening device provided in the housing for opening the supplied sliver, and a fiber opening device rotatably supported in the housing around a rotation center axis and diametrically supported. a drum rotor having a deposition surface on which fibers are to be deposited on its inner surface; a drive device for rotating the drum rotor; and fibers opened by the fiber opening device toward the deposition surface of the drum rotor. a passageway for supplying the fibers together with an air flow; a base supported by the housing so as to be rotatable about the rotation center axis; a support arm extending radially outward from the base; is provided at the end of the drum rotor, with one end opening facing the inner surface of the drum rotor and the other end opening facing the rotation center S.

A hole is provided in the guide portion of the guide member so as to be eccentric about 7 with respect to the central axis of the cylindrical passage and open into the cylindrical passage, and a hole is provided in the cylindrical passage in a direction oriented toward the rotation center axis. an injection nozzle formed to emit a swirling air flow to the air; and a heating scissors consisting of a passageway, and the heating scissors are arranged opposite to each other at an appropriate interval between a rotating surface formed by the radial tip of the guide portion of the guide member and the inner surface of the drum rotor. a linear teflector protruding from the housing and having an arcuate surface formed at a position close to the center axis of the cylindrical passage of the guide section, and the center axis of the cylindrical passage; The drum rotor's rotational speed and guide are provided at a position on the extension of the drum rotor and are comprised of a pick-up port for gripping the fiber bundle led out from the cylindrical passage of the guide portion of the guide charge. A speed difference corresponding to the yarn withdrawal speed is provided between the rotational speed of the member and the deposition of fibers on the deposition surface of the drum rotor and the withdrawal of fiber bundles from the deposited fiber layer at appropriate speeds. Since the heating device for the fiber bundle is formed at the end of the supporting arm of the guide member, the fiber bundle separated from the deposition surface of the drum rotor can be heated to a heating device disposed on the extension of the central axis of rotation of the drum rotor and the guide member. While being pulled out by the up roller, a swirling air flow is applied to the fiber bundle within the inside of the guide member to cause false twisting and binding, and the inner surface of the drum rotor and the rotating surface of the guide portion of the guide member Since the deflectors projecting from the housing at intervals are formed in an annular shape, the fiber bundles separated from the deposition surface of the drum rotor are guaranteed to contact the arcuate surface of the deflector, thereby preventing flattening of the fiber bundles. Free fiber formation can be ensured.

Further, in the device of the present invention, two guide portions are provided at the end of the support arm at nine positions at 180 degree intervals around the rotation center axis of the guide member, and each of these guide portions is provided with a cylindrical passage. If the configuration is such that two fiber bundles are pulled out from the M-area surface of one drum rotor by providing a heating device and a shaping device to bind and tie each fiber bundle, one guiding device can be provided. The production of yarn can be doubled compared to the case where a section is provided, and in addition, since the guide member has a symmetrical configuration with respect to the rotation center axis, the quiet balance and dynamic balance are improved, and the rotation support of bearings etc. can improve the durability of

In the spinning device, the drum rotor is rotatably supported by the housing at its outer periphery in the diametrical direction via a bearing, and a pulley portion is formed at the outer periphery, and the guide member is supported by the housing at the h+1 base portion via a bearing. When the pulley portion is rotatably supported and formed on the base, the drum rotor and the guide member can be easily supported concentrically with respect to the housing and rotated by a belt, and the drive mechanism can be simplified. Furthermore, when the guide member is provided with two guide parts, instead of pulling out the threads led out from each guide part separately by a pick-up roller and winding them onto separate cheeses, the thread is drawn out by the pick-up roller. It is also possible to arrange a pick-up roller to simultaneously pull out the thread and tighten the gold thread.
